flexible cord connection from a ceiling service panel to a lab casework-mounted disconnect switch?

[SeniorElectricalEngineer]

I am working on a lab project where the client desires maximum flexibility, so the architect proposed a flexible cord connection from a ceiling service panel to a lab casework-mounted disconnect switch.

Is this allowed by NEC? Or any other codes you are aware of?
